The effects of using ascorbic acid (AA), rosemary extract (RE) and a-tocopherol/ ascorbic acid (T+AA) were evaluated on some quality characteristics of chicken patties stored at -20°C for 6 months. On 0th day and 2nd, 4th and 6th months of storage period, TBA, non-heme iron and colour parameters were measured and sensory evaluation was performed on chicken patties. At the end of the storage period patties with T+AA had the lowest TBA values. Non-heme iron content indicated no difference during storage and among treatments. On month 4 and 6 no differences were found on flavour scores between treatment groups.
